/* ** ** Swift/XRT hardness ratio for OJ 287. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 56740.390483 0.001220 0.49728 0.13726 1.00000 1 0.23277 0.03728 0.19025 0.03046 0.11575 0.02602 0.09475 0.02130 56740.392691 0.000988 0.56105 0.15883 1.00000 1 0.25328 0.04357 0.20860 0.03589 0.14210 0.03195 0.11704 0.02631 56740.394507 0.000828 0.53859 0.15149 1.00000 1 0.31476 0.05320 0.25926 0.04382 0.16953 0.03811 0.13963 0.03139 56740.396207 0.000872 0.78595 0.23579 0.98333 1 0.20967 0.04193 0.17242 0.03448 0.16479 0.03685 0.13559 0.03032 56740.398095 0.001017 0.52530 0.14666 1.00000 1 0.26411 0.04415 0.21756 0.03637 0.13874 0.03102 0.11429 0.02556 56740.400245 0.001133 0.47376 0.12290 0.96178 1 0.30174 0.04459 0.24810 0.03667 0.14295 0.03048 0.11731 0.02501
